The Barbara Mullenix story, the CSI Actress (extra) murdered by daughter Rachael Mullenix, is on 48 Hours again tonight. Barbara Mullenix (photos below), a CSI extra, was first covered by LALATE back in October of 2008. Tonight, a rebroadcast of CBS’ 48 Hours looks at the case, the interrogation of Rachael, and the mystery behind the murder. Below is video from that broadcast.

Rachael Mullenix, 19, was from Huntington Beach. She was sentenced to twenty five years to life. A jury found that Rachael conspired to kill Barbara with her boyfriend and then dumped her mom’s body in Newport Harbor.

Mullenix was 17 when the murder occurred. She maintains she didn’t commit the crime. “I don’t care what the jury thought. I did not do that to my mother. I can’t even believe this is happening to me.

“Even though I didn’t do it. I feel like I didn’t do enough to prevent it.” Her father agrees that his daughter didn’t commit the crime. Her father, divorced from Barbara whom he describes as an abusive alcoholic, reportedly says his daughter didn’t do it. “I know in my heart that she didn’t do this”.
